A miniaturized microstrip Wilkinson power divider with harmonics suppression using radial/rectangular-shaped resonators

ABSTRACT

In this paper, a new power divider (PD) is designed initially; then a new PD has been proposed by replacing the conventional transmission lines with rectangular-shaped and radial-shaped resonators. It results in the extra harmonics suppression with a miniaturized circuit size. The proposed PD has been analyzed using even-mode/odd-mode analysis. The designed PD shows a very good fractional bandwidth. In addition, the proposed PD is miniaturized 41% approximately. Also, seven harmonics are eliminated. Finally, PD was implemented and the experimental results illustrate a good agreement with simulation results.
